大連配電箱帶有(you)器具(ju)的鐵制(zhi)盤(pan)面和(he)裝有(you)器具(ju)的門及電器的金屬(shu)外殼均應(ying)有(you)明顯可(ke)靠的PE保護地(di)線（PE線為黃綠(lv)相間的雙色線也可(ke)采用(yong)編織軟裸銅線），但PE保護地(di)線不允許(xu)利用(yong)箱體(ti)或(huo)盒(he)體(ti)串(chuan)接。

    配(pei)(pei)(pei)電(dian)(dian)(dian)系統(tong)應設(she)(she)置(zhi)室(shi)內總配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)和室(shi)外分(fen)配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)或設(she)(she)置(zhi)室(shi)外總配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)各分(fen)配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)，實(shi)行分(fen)級(ji)配(pei)(pei)(pei)電(dian)(dian)(dian)。動力配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)與照明(ming)配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)宜分(fen)別設(she)(she)置(zhi)，如(ru)合置(zhi)在同一配(pei)(pei)(pei)電(dian)(dian)(dian)箱(xiang)內，動力和照明(ming)線路應分(fen)路設(she)(she)置(zhi)。

    大連配(pei)(pei)(pei)(pei)電(dian)(dian)箱應(ying)由末(mo)級分(fen)(fen)配(pei)(pei)(pei)(pei)電(dian)(dian)箱配(pei)(pei)(pei)(pei)電(dian)(dian)。總配(pei)(pei)(pei)(pei)電(dian)(dian)箱應(ying)設在靠近電(dian)(dian)源(yuan)的(de)地區。分(fen)(fen)配(pei)(pei)(pei)(pei)電(dian)(dian)箱應(ying)裝設在用(yong)(yong)電(dian)(dian)設備或負(fu)荷相對(dui)集中的(de)地區。分(fen)(fen)配(pei)(pei)(pei)(pei)電(dian)(dian)箱與開(kai)關(guan)箱的(de)距離(li)不(bu)得超(chao)過(guo)30m。開(kai)關(guan)箱與其控制(zhi)的(de)固定式用(yong)(yong)電(dian)(dian)設備的(de)水平距離(li)不(bu)宜超(chao)過(guo)3m。

    大連配(pei)電(dian)箱(xiang)內的電(dian)器(qi)應首(shou)先安(an)(an)裝在(zai)非金(jin)屬(shu)或木質的絕緣電(dian)器(qi)安(an)(an)裝板上，然后(hou)整體緊(jin)固在(zai)配(pei)電(dian)箱(xiang)箱(xiang)體內，金(jin)屬(shu)板與(yu)鐵質配(pei)電(dian)盤箱(xiang)箱(xiang)體應作電(dian)氣連接。
